My SSD is currently running as the C drive on a laptop and it will continue to do that at least until it's up to 35TB, which is the expected life based on 20GB per day for 5 years.

So, 1/3 of the drive is filled with static data (W7 x64) an the rest is used for writes. The app fills the drive with random sized files ranging from 1KB up to 12MB in size.
More than 50% of the files are 128KB or smaller in size.
TRIM is active.

I'll be posting the first update within an hour or two, it's almost 24h since I started and thought that an 24hour update would be interesting.

1) The SSD maintains its capacity
2) The SSD maintains the required UBER for its application class
3) The SSD meets the required functional failure requirement (FFR) for its application class
4) The SSD retains data with power off for the required time for its application class

New thread created for the SF2XXX issues Link

There is always at least 12GB of empty space. My conditions are very similar except that I don't have my windows running on the drive (I did place 11GB of static data on it to compensate). I am having some difficulties with the PC I am using for this crapping out so I am not going 24/7. Maybe 18h a day due to BSODs. I am only at 1.5TB so far.

Yeah, it's the app I've been developing, it started out as a small utility for importing iometer result files and now it includes a storage benchmark and a lot of WMI stuff, I've been adding some SMART stuff as well but that part isnt ready yet.

A download link is coming your way soon
(maybe this week)

It doesn't look like it's slowing down, we'll see later tonight, will be posting an update at about 5TB Host Writes.
(there has been some development on the SMART attributes, nothing alarming though)

I've been checking a few things wrt SMART attributes on the Kingston vs the X25-V and they are identical as to what attributes are reported.
There was a question at the Intel forum about attributes E2-E4 on the Kingston V40 as it was showing 0xFFFF (65536) on my drive and apparently there was an issue with the log, I ran smartmontools and it looks like it cleared the condition.

Anyways, those attributes are not reported by any of the Intel SSD Toolboxes and afaikc they don't mean squat on the old series (as in not being documented), I even updated from 02HD to 02M3 on one of my Intel X25-V's and it didn't change a thing,

I've caught up to you in writes but my wear indicator is at 98 with all other parameters not having any changes. I guess I don't feel as if there is anything interesting going on yet. Probably nothing interesting will happen at the very least until 30-40TB mark. I do not expect it to last past 100TB, but we will see.

Its incredible really. A 40GB drive is writing 71 times its capacity a day. The 320 has less PE, but can cache writes to offset wear. So far it looks like half the wear on the 320 compared to the X25-V for the same amount of writes.

What will be really interesting is how much more the drive can write when the wear out indicator gets to 1. I suspect the wear out indicator is based on an arbitrary PE value as opposed to the actual PE capability of the NAND. Should soon see though.

Someone should try this on an SF drive to see what happens. Anvil are the randomly generated files compressible?

I did actually look at todays offerings and found the 60GB SF on special offer at $140 which is extremely cheap considering the prices in Norway.
I'm just wondering whether I'm up for it or not, it does require a bit of attention and the SF drives would require a lot of work compared to other drives that don't throttle.

It would be interesting to know how fast one would reach full throttle and if full throttle is bearable.

I can pick up a V2 40GB drive really cheap. I'm hesitant however. If throttling kicks in it will take forever so I don;t want to do it on my main pc. I'll scrat around and see if I can build a pc from spare parts.

So 5TB roughly = 4%...
I'd say the drive should perform well enough even after 50TB in this case. And the death would occur after 125TB. At least according to the current results. So much for 15TB endurance claims... We'll see, though.

Edit: the wear speed should accelerate due to dying cells and thus, spare area getting smaller over time, though.
